The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done further description.
Referring to Fig. 1, Fig. 2, Fig. 3; A kind of dust-proof mechanism of child lock of the present invention; Comprise latch mechanism 1, handle 2 and protective cover 3, said protective cover 3 is provided with groove 32, and said latch mechanism 1 is connected with said handle 2 through said protective cover 3; Said protective cover 3 bottoms are provided with chute 31, and said chute 31 is connected with the slide plate that is provided with perforation 34; The said slide plate 34 of said handle 2 break-through; Said slide plate 34 can slide in said chute 31.In this embodiment, protective cover 3 is mounted on the slippage door inner panel, in child lock mechanism 1 is mounted on the opening apparatus; Stir up and down through operating grip 2; Sliding pin in promoting on the opening apparatus slides, and realizes that the child lock unlocking/locking ends function, thus the protection child safe; And, set up protective cover in order to prevent the dust child lock of from the square hole of child lock, entering.
Said chute 31 is linear or arc; Said slide plate 34 is arc mechanism or planar shaped mechanism.Chute 31 is located at the two bottom sides of protective cover 3, can be linear or arc; Because said slide plate 34 is used with this chute 31 together, therefore when chute 31 be linear, said slide plate 34 be that cooperate with it also can be along the straight plate of chute 31 slips, and when this chute 31 was arc, equally, said slide plate 34 also should be arc mechanism.The structure of a said chute 31 and a sealing of slide plate 34 formation prevents that dust from getting into child lock from groove 32.
Like Fig. 2, said protective cover 3 both sides are provided with edge projection 33; Said edge projection 33 can be square, triangle, circle or special-shaped; Said edge projection 33 is symmetrically distributed in the both sides of said protective cover, through using this edge projection 33, can let protective cover 3 and other mechanism press fit together, thereby this dust-proof mechanism of child lock is packed in the slippage door very easily.
Fig. 5 and for example, said latch mechanism 1 is positioned at the end 11 that is connected with said handle 2 and is provided with helicitic texture, and said screw thread is an internal thread; Said end 11 structures are column construction, are cylindrical structural in this embodiment.
Be provided with a raised step 22 with reference to the said handle 2 of figure 3, Fig. 6 and Fig. 1; One side of said raised step 22 is a screw rod 21; Said handle 2, said raised step 22 and said screw rod 21 are consolidated into one through the extension mode of moulding; Said screw rod 21 is connected with said end 11; The diameter of said raised step 22 is greater than the diameter of perforation on the said slide plate 34, and the diameter of perforation is greater than said end 11 diameters on the said slide plate 34.Said screw rod 21 is for inlaying screw rod, and this end 11 of inlaying screw rod and latch mechanism couples together handle 2 and latch mechanism 1 through being threaded, and guarantees that this handle 2 can untie and lock child lock.In this embodiment; This handle 2 passes slide plate 34 and is connected with said latch mechanism 1; Thereby said handle 2 is kept apart with said latch mechanism 1, and said handle 2 passes the groove of said protective cover 3 simultaneously, is convenient to handle move up and down at slippage door inner face; Said handle 2 and said slide plate 34 seal the bottom of said protective cover 3, thereby prevent that dust from getting into along the bottom of groove from protective cover 3.And said slide plate 34 is positioned at 1 of said handle 2 and said latch mechanism, and said handle 2 and said latch mechanism 1 can be adjusted the gap of 3 of said slide plate 34 and said protective covers as the case may be, are convenient to the position of adjusting slider, thereby eliminate manufacture deviation.
Said handle 2 is a cylindricality; Said handle 2 can move up and down in said groove 32; When said handle 2 moved, said slide plate 34 was along with this handle 2 moves together, thereby guaranteed that this slide plate 34 covers the groove 32 of this protective cover 3 all the time under motion or inactive state.
In a kind of specific embodiment, child lock protective cover both sides have edge protruding, are convenient to the child lock protective cover is stuck on the door-plate; And arc chute is arranged at child lock protective cover bottom, is convenient to slide plate on arc chute, slidably reciprocate; The child lock handle with inlay screw rod and mould the mode strong bonded together through extension; This outstanding end of inlaying screw rod is threaded; Cooperate with the screw thread on the child lock mechanism end; Be convenient to adjust the gap between slide plate and child lock protective cover, no matter the child lock handle pushes or upper/lower positions (locking or release), can both realize the dustproof function.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
